Extang Trifecta E-Series Tri-Fold Tonneau Cover for RAM 1500 DT 5'7"

The RAM 1500 with Rambox has integrated storage compartments built into the bed sides, which alter the bed rail and flange profile. The non-Rambox variant suits a standard RAM 1500 bed, and the Rambox version is specifically cut to account for the different rail geometry. Selecting the wrong variant will result in a poor fit at the bed rails and seals, so confirm your truck's configuration before ordering.

The Trifecta E-Series clamps to the bed flanges and the tonneau rails sit above the tray floor. Factory tie-down points in the tray floor remain accessible when the cover is removed. With the cover closed, side-rail anchor access will be restricted. Plan your tie-down points accordingly.

The Trifecta E-Series for the RAM 1500 includes a 5-year manufacturer warranty. Refer to the included warranty documentation for the specific terms and conditions.

Yes. The E-Series can be driven with the cover folded fully forward toward the cab. Integrated buckle straps secure the cover in the open position while you are on the move.

The vinyl tarp is designed for UV and weather resistance under normal use. Prolonged exposure to intense direct sun over many years can affect the suppleness of vinyl in any soft cover. The aluminium support bows help maintain shape and prevent sagging. Parking in shade when practical is a sensible habit for any soft fold cover.

Soft covers like the E-Series are primarily designed for weather protection and convenience rather than as a secure lockable barrier. They act as a deterrent against opportunistic access, particularly when paired with a locking tailgate. If cargo security is a priority, a hard folding cover with rigid panels provides a significantly stronger deterrent.

Yes. The Trifecta E-Series arrives fully assembled and uses a clamping system to attach to the bed flanges without drilling. No modifications to the truck are required. Most owners complete the installation at home in under 30 minutes.

The Trifecta E-Series is designed to work with a standard drop tailgate. You drop the tailgate to fold the cover open or access the rear of the tray. The spring-loaded clamps release cleanly and the panels fold forward once the tailgate is lowered.
